Abstract

Escherichia coli O157:H7 is a contaminant of beef products and has been associated with food-borne illnesses in humans. Recently an E. coli SRP® vaccine received conditional licensure in the United States for the control of E. coli 0157 in cattle. E. coli is also a common disease agent responsible for causing postnatal calf diarrhea. Colostrum management is recognized as an important factor for calf health and survival. Calves that fail to consume an adequate amount of colostrum within the first 12-24 hours after birth are at a higher risk for disease, death, and decreased performance. The objective of this study was to determine if E. coli O157:H7 SRP®-specific antibodies could be detected in the serum of calves that consumed colostrum from dams that were vaccinated prior to calving with E. coli O157:H7 SRP®-vaccine.
